Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Apparently, the unit is not able to power on. Outside of a possible issue with the remote controller's interaction, either the television unit is not receiving enough electrical current to so do (to power on), or it has an issue at the circuit board level. If it is not receiving enough electrical current, then the power adapter could be at fault.

The manufacturer makes no mention of an energy conservation switch on this unit other than the power/standby button on the television unit. Ascertain that you have the appropriate remote for this television unit. (The button locations later mentioned refer only to the original remote controller supplied by the manufacturer.) Clear obstructions from the front of the television so that nothing hinders the remote controller's pathway to the television unit's receiver. Try powering on the television unit by using the remote controller (USING THE RED BUTTON AT THE TOP END OF THE REMOTE CONTROLLER-NOT THE "TV" SOURCE BUTTON ON THE FOURTH ROW OF BUTTONS). Then try powering on the television unit by pressing the aforementioned power/standby button directly on the television unit.

If the remote controller does not power the television unit on but the unit's direct button does, then the remote controller apparently has a problem in either its battery power or some aspect of its function (the contact(s) on the keypad could be defective or gaining resistance). Test for the resistance issue by continuing to depress the remote controller's power button until the television responds or for up to ten seconds (whichever occurs first). If the remote controller does not initially power on the television unit until after a delay during this remote controller keypad resistance test then the remote controller should be replaced. If the remote controller only turns the television unit on when closer than the usual distance from which it is normally used or not at all, then try again after replacing its batteries & make sure that the battery contacts are clear of any obstruction (such as debris, plastic, an object, or corrosion). If the remote controller still does not power on this television unit (but the unit's direct button does) then the remote controller could be faulty.

The power adapter's design specifications for electrical current are listed either on the power adapter or on the back of the television unit (either near the power inlet or wherever the majority of model information is presented). The power adapter's specifications will have a symbol arrangement with a - or a + on the outside of a C with the opposite - or + on the inside of that C. The manufacturer uses the C to represent the power connector (the end that plugs into the television unit) in terms of which polarity of electricity is set to flow internally & which polarity of electricity is set to flow externally to the round pole of the power connector. For television units sold in the United States of America, the - represents negative current, & the + represents positive (hot) current; & this AC/DC power adapter transforms the building's/household's alternating current (AC) into direct current (DC).

WARNING: ALWAYS REFER TO SAFETY GUIDELINES WHEN HANDLING ELECTRICITY OR ELECTRICAL DEVICES (http://www.electricalsafety.org/). FIRST, REFER TO THE MULTIMETER'S INSTRUCTIONS TO TEST YOUR MULTIMETER! (A multimeter is separate device used to determine the presence & amounts of varying electricity conditions. It is a separate tool that should be in your own tool kit.) Using a multimeter, a person could test for continuity & for the DESIGN-SPECIFIED levels of amperage & of voltage.

A power issue could exist in any one or combination of areas including (but not limited to) the power outlet, any indirect power source through which the television unit is perhaps connected (such as a surge suppressor/protector, a power tap device, or an unlimited power supply (UPS) device), the power adapter &/or an internal television unit component/condition. If the power adapter fails at this power outlet, then take it to a different room & test it, again. If it passes at the initial location, then the television should be serviced by a professional. If it fails at either location but not at both, then the power outlet in which it failed would appear to have a problem * (* = not necessarily the television unit's only problem). If it fails while plugged into an indirect power source device, then try again after resetting the power to that device. If resetting the indirect power source device proves unsuccessful, then temporarily bypass that device by plugging the power adapter directly into the power outlet. The indirect source of electricity could be defective *. If the power adapter fails in every test, then the power adapter is at fault & should be replaced *.

SOURCE: Westinghouse LD-4655VX Power on fine, nice picture, but around 5 minutes turn off self it,

If the set is still under warranty, the power supply board is going bad. If not you can replace it yourself. It's not that big of a job. You can find the parts you need at www.shopjimmy.com

Westinghouse LD 2480 wont power up


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
